Which equation has a solution of t = 14?
Construct a scatterplot and identify the mathematical model that best fits the data. Assume that the model is to be used only for the scope of the given data and consider only linear, quadratic, logarithmic, exponential, and power models. Use a calculator or computer to obtain the regression equation of the model that best fits the data. You may need to fit several models and compare the values of R2.
y = 8.14x0.58
y = 7.04 + 2.36x
y = 0.01x2 + 2.19x + 7.53
y = 4.40 + 12.02 ln x
Answer: i think its y=8.14x0.58

Sapatra spent $80 at Mr. and Mrs. Crab. She left a tip of 20%. How much was the tip she left?
Answer:
$16
Step-by-step explanation:
So Sapatra spent $80 at Mr. and Mrs. Crab and She left a tip of 20%. We can convert 20% into a decimal, that would be .2 when you move your decimal from the left 2 times and multiply 80 by .2. meaning her tip she left is $16

After sales tax, A $96 watch costs $101.28. what is the sales tax percentage?
Answer:
i think it's 5.5 percent
Answer: The answer is 5.5% sales tax percentage
Step-by-step explanation:
First, subtract the total amount by the original amount
$101.28-$96= 5.28
Next, you would divide 5.28 by 96
5.28/96 = 0.055
The final part in which to get the answer is to multiply 0.055 with 100%
0.05·100= 5.5%

ΔABC is an isosceles triangle with AB = AC, D is the midpoint of BC and
AD is joined. Prove that ΔABD ≅ ΔACD.
I kinda have a problem with triangles and congruency....little help please ?
Step-by-step explanation:
Okay, so the triangle would look something like this:
see the image attached
Since AB=AC, which is given; <ABD = <ACD, because they are the angles opposite from the congruent sides of the isosceles triangle; and <ADB=<ADC, as AD is the bisector*; ΔABD ≅ ΔACD using SAA/AAS (side-angle-angle) congruencey.
*If the bisector of an angle in a triangle meets the opposite side at its midpoint, then the triangle is isosceles, and vice versa

Does anyone have any ideas for multiplying 249 times 398 quickly and mentally? Everything online is too complex.
Answer:
So, the first solution is a calculator but sometime we don't have a calculator so, do
200 X 300 = A
40 X 90 = B
9 X 8 = C
then add just do multiplication from there like
A + B = D
D + C = E
Then your finally answer would be E
Hope that helps that's the way I do math quick in my head
(Btw the answer to 249 X 398 = 63,672 )
I dont understand index form please help
When we multiply powers with the same base, we add the powers together. This will give us:
[tex]\frac{3^8*3^4}{3^2 * 3^8} \\\frac{3^{12} }{3^{10}}\\[/tex]
When we divide the fractions with the same base then we subtract the exponents:
3^12 / 3^10 = 3^12-10 = 3^2

Suppose Enrique has two building blocks. The area of one face of one of the blocks is 4 square centimeters and the area of the face of the other block is 100 square centimeters. What is the scale factor from the smaller block to the larger block?
Answer:
I think the larger block has a scale 25 times bigger than the smaller block since 100 divided by 4 equals 25
Please tell me if I'm wrong
I hope this helps
:D
Answer:
The Scale factor is 5.
Step-by-step explanation:
Because the area has cm^2 to find the scale factor you find the number it takes to get from one area to the next and take the square root.
4X = 100
X = 100/4
X = 25 (Take the sqrt because of area)
X = sqrt(25)
X = 5
The Scale factor is 5.
To make orange fizz, Noah mixes 4 scoops of powder with 6 cups of water. Andre mixes 5 scoops of powder with cups of water. Create a double number line or a table that shows different amounts of powder and water that taste the same as Noah’s mixture.
Answer:
Noah mixes 4 scoops of powder with 6 cups of water.
Means Noah ratio will be or 0.67
Andre mixes 5 scoops of powder with 8 cups of water
Means Andre ratio will be or 0.62
As, or 0.66 > 0.62
We can say that content of orange powder will be more in Noah mixture than in Andre's Mixture.
Hence, Noah's mixture will taste more like orange, than Andre's mixture.

What is 4 3/10 plus (-6.2) in decimal form
Answer:
Step-by-step explanation:
First change 4 3/10 to 4.3. Then you change 4.3 + -6.2 to 4.3 - 6.2.
Then you do 4.3 - 6.2 and you should get - 1.9.
Answer:
The answer is (-1.9)
Step-by-step explanation:
4 3/10 = 4 × 10 + 3/10 = 43/10 = 4.3
Now,
4.3 - 6.2 = -1.9
Thus, The answer is (-1.9)

Use this information to answer Parts A, B, C, and D.
Regina is buying a new car. She sees two advertisements in the paper for the same car at two different prices from two different dealerships. Both dealers are offering a simple-interest loan for the price of the car.
A photo of car includes two ads. Ad A shows the vehicle priced at twenty-four thousand two hundred dollars at six point five percent interest and an unknown number of years. Ad B shows an unknown price, at a five point three percent interest over nine years.
Part A
Regina calculates that to buy the car in Ad A, the loan would ultimately cost her $41,503. Over how many years is the loan in Ad A to be paid back?
Part B
Regina calculates that to buy the car in Ad B, the loan would ultimately cost her $38,402. What is the price of the car offered in Ad B?
Part C
In either case, Regina would be paying back the dealer in equal monthly installments over the lifetime of the loan. What would her monthly payments be if she bought the car shown in Ad A? What about if she bought the car shown in Ad B?
Part D (Its a multi-pick question, so you don't need to answer)

If the perimeter of a regular pentagon can be expressed as 10s - 20, determine the length of each side.
50 s - 100
5 s - 10
s - 2
2 s - 4
Answer:
2 s - 4
Step-by-step explanation:
A Regular pentagon means that it has 5 evenly lengthen sides. In other words, the shape with 5 sides has lengths are equal to each other.
Because the total perimeter as mentioned of the pentagon is 10s - 20,
dividing it by 5 should find the length of each side!
Equation: (10s - 20) / 5
Once you finish dividing each digit inside the bracket you are done!
= 2s - 4
So that leaves us with 2s-4
Answer:
2 s - 4
